STATIONARY-C AN DOUBLE-SEAMING MACHINE.

Specification of Letters Patent.

Patented Jan. 21, 1908.

To all 107mm it may concern.

Be it known that l, FRANK Runobrrn, i citizen of the United States, residing in (,lif. v cago, in thecunt of Cook and State of lllinois, have invented a new and useful improvement in Stationary-(fan Double-Seaming -i lachines, of which the following; is a specification.

My invention relates to double seaming -1O machines for seaming the heads or covers upon sheet metal cans, and, more particularly to double seaming machines of the kind or class in which the can is held stationm-y during the scanning operation, and which are .15 specially designed for seaming the covers on and perfectly double seamed cntilled cans.

My invention consists in the means 1 em ploy to practically accomplish this object or result; that is to say, it consists, in connection with a can feed table or guide track,

along which the cans may he fed or moved,

one hy one, an intermittently movable endless tlexihle can feeder or chain having can pusher arms thereon for feeding or moving the cans,.one hy one, intermittently along the can feed tahle or track, a vertically re ciprocating chuck or plate upon which each can in turn is delivered by the feeder, a pair of horizontally reciprocating can clamping jaws [or clamping and centering the can to '40 he seamed with the upper can clamping chuck or plate and with the rotary seaming head, an upper can elamping chuck or plate eoi'iperating with said lower reciprocating chuck orxplate tolirn'ily clamp aml hold the cover-on the can hody preparatory to and during the-s aming operation. a contirmousl) teed table or track It, upon hie I each can in rotating seaming head carrwing a plurality of seaming rollers. each mounted upon a separate vihratihg lever hinged to said sunning head. and a continuou ly rotating can wheel mounted upon the s aming head and rotating llifiltlit'lltlt'lltly llu'ltllt and at a slightly \ariant speed to cause the cam wheel s to provide Appiicatinn iiled'oiztober 3Q, 1905. Serial No.284-9Z7.

to turn slowly in'respeet to the seaming head and thus cause the cans of the cam wheel to operate the several seaming roller levers in proper time and succession.

My invention also consists in the novel construct ion of parts and devices and in t he. novel oml'iinations of parts and devices herein shown or descrihcd in the accompanring drawings, forming a part of this specification, Figure .1 is a front elevation of a stationary can douhle seaming machine elnhod \'ing my invention; Fig. 2 is a siderleration'.

G is a rapidly and continuously rotating seaming head rigidly secured to the hollow seaming head shaft G, surrounding the hollow stem E upon which the upper stationary chuck E is supported. The rotary seaming head G carries two airs of seaming rollers, onepair 9 9 being orming rollers, and the other pair g g finishing rollers, the forming rollers coming first into action to curve or fold the flange 2; of the cover '21 about the flange I of the can body X, and the finishing rollersg 9" coming next into action to finish the formation of the 5- am and compress its several folds or flanges snugly and closely toether. The rotary seaming head G has four ugs or projections G referabiy formed integral therewith, tov wliieh the seeming roller le v'er's g andg are pivotarly connected or hinged by suitable pivots g. The seaming tools or rollers g g are rotatably mounted upon their carrying levers g? g by suitable studs 9 secured in place by set screws 9. The operating levers g fupon which the finishing rollers g are mounted, are preferably furnished with an additional separate piece or adjustable arm 9 pivotally connected to the lever g by the pivot pin 9*, the arm 9 being additionally and adjust-ably and yicld-- ingly connected to the lever g by an arm or projection g", havin a slot through which passes a stop bolt g aving a split adjusting nut 9 which is firmly fixed in any position to which it may be turned by a set screw 9;

the lever 51 having also an arni g furnished "with aspring 9 interposed between said arm and the bin ed and adjustable arm g.

The arm 9" of the lever g is also furnished with an adjusting screw g for "urther regulating the tension of the spring 9 and thus the yielding connection between the lever g and its hinged arm .9 Each of the seaming '-roller operating levers g '9 is furnished with an anti'friction roller 9 journaled upon a suitable stud g" fixed in place by a set screw 9" for ur oseof en agement with the rotary.
